This opinion is limited to the Federal law of the United States and the applicable statutory provisions of Chapter 78 of Nevada Revised Statutes, and we express no opinion as to the laws of any other jurisdiction. This opinion is rendered pursuant to Item 601(b)(5)(i) of Regulation S-K under the Act.
